Welding Sheet Metal Calculator

Welding & Sheet Metal Toolkit is a professional calculator suite built for welders, fabricators, sheet-metal shop owners, weld inspectors, and CNC machinists. Everything runs fully offline, so you can price a weld, size a blank, or check heat input right on the shop floor without cell service or Wi-Fi. Stop juggling scraps of paper, dusty handbooks, and half-broken spreadsheets. Get 11 focused tools in one clean app, built around real AWS and ASME workflows. WHAT'S INCLUDED: Welding - Weld Cost Estimator (FREE): Price any joint by wire, gas, labor, and deposition rate. - Weld Parameters Guide: Recommended amps, volts, wire feed speed, polarity, and shielding gas for SMAW, GMAW (MIG), FCAW, and TIG across common thicknesses. - Welding Heat Input: Calculate heat input in kJ/in or kJ/mm for procedure qualification and WPS records. Sheet Metal & Forming - Bend Allowance: K-factor based bend allowance, bend deduction, and setback for press brake work. - Flat Pattern Development: Develop accurate flat blanks from finished part dimensions. - Stamping Tonnage: Estimate press tonnage for blanking and piercing from perimeter, thickness, and shear strength. Surface Treatment - Dry Film Thickness: Convert wet film to DFT and plan coating coverage and consumption. - Sandblast Rate & Cost: Estimate blast time, grit use, and cost per square foot by profile and nozzle size. Mechanical & Fiber - CNC Thread Drill Hole (FREE): Tap drill sizes and thread chart reference for machinists. - Pulley Belt Length: Calculate belt length for two-pulley drive systems. - Fiber Splice Time (FREE): Estimate fusion splice time for fiber optic jobs. WHO IS IT FOR: - Welders running SMAW / stick, MIG, and TIG in the field or shop - Fabricators and sheet-metal shop owners quoting jobs - Weld inspectors checking heat input and procedure compliance - CNC machinists and tool room techs - Manufacturing and welding engineers writing WPS and PQR WHY WELDERS & FABRICATORS LOVE IT: - Fully offline. Works in bays, basements, and job sites with zero signal. - No ads, no tracking, no subscription traps. - One-time unlock. Buy it once, use it for years. - AWS and ASME aware formulas for heat input, bend allowance, and tonnage. - Professional accuracy with clean, fast input forms designed for gloves and bright sunlight. ONE-TIME UNLOCK: Unlock All Calculators is a single $12.99 USD non-consumable in-app purchase. It unlocks all 8 Pro calculators plus reference tables, forever, on your Apple ID. No recurring fees. Price a weld, develop a flat pattern, and log heat input from the same app, all before the next bend cycle finishes.
